Question

If y = 6x + 1, find y when x = 9

Answer 1

55

Explanation:

if x=9 and y = 6x + 1

then all what you have to do is that you should substitute x by 9 in y equation as the following,

y = 6*(9) + 1 =54 + 1 = 55

Answer 2

55

Explanation:

Given,

y = 6(x)+1

• x = 9

Substituting x= 9 on the given expression,

• y = 6(9)+1
• y = 54 + 1
• y = 55

Hence y = 55.
